Cisco PA-2102-1-LF 1025 Watt Switching Power Supply Catalyst 2960-X

Description

The Cisco PA-2102-1-LF is a high-capacity 1025-watt AC switching power supply designed primarily for the Cisco Catalyst 2960-X and 2960-XR series switches. It provides the heavy-duty power required to support extensive Power over Ethernet Plus (PoE+) budgets, enabling the switch to provide power to numerous high-demand devices like IP cameras, VoIP phones, and wireless access points.

Core Product Overview

This power supply is an internal, hot-swappable module that enhances the reliability and power capacity of your networking hardware. In the 2960-XR series, it can be used as a primary or secondary redundant power supply to ensure “zero interference” in network uptime. Its high wattage is essential for 48-port PoE+ configurations where a significant power budget (up to 740W of PoE) is required across all ports.
